Packaged boiler skid system

The work at the Moto Services Area on the A1 near Grantham in Lincolnshire was carried out by George Birchall Service, one of the UK's largest providers of reactive and planned maintenance in the building services sector. Moto Hospitality's own engineers oversaw the design and delivery of the project.

The specification of the compact and easy to install Stokvis R40 Modupak boiler skid system features not just the trio of R40/120 fully modulating, fully condensing boilers, but also all necessary boiler pumps, safety valves, isolation valves and associated pipework. In order to ensure the long term performance and reliability of the boilers, the Stokvis Modupak incorporates a Spirocross Air/Dirt separator which removed dirt and air from the system.

Andy Clay, contract manager for George Birchall Service, explains: "We have been undertaking maintenance and replacement work across some 50 sites operated by Moto for a decade now with many of them featuring the installation of Stokvis Energy Systems boilers, Econoplate Packaged Plate heat exchangers and associated equipment. Moto prefer to use Stokvis equipment and we know we can rely on a very good level of support from the company, including the full manufacturer's commissioning once our installation is complete.

"In the case of Grantham, the existing boiler house is very cramped and of an age when you have to take full account of the possible presence of asbestos. For these two reasons, and because the original single boiler offered no back-up, we decided to install a Stokvis Modupak incorporating a three boiler set up using an integral controller to create a cascade/sequencing arrangement. This not only offers very good and reliable output, but avoided any need to fix anything to the walls of the old plant room. The Modupak framework comes ‘flat packed', is easy to install and assemble and includes all the manifold connections, pumps, associated pipework and a low loss header or Spirocross Air/Dirt separator as required or requested.

"Completed last summer, the new boilers feed the rooftop AHUs and the radiators - through a low pressure hot water circuit - and provide all the DHWS for the site via a Stokvis Econoplate Packaged Plate Heat exchanger. The project has been a real success."
